Specification of Letters Patent.

Patented Dec. 11, 1906.

Application filed A t 9. 1899. Serial No. 726,662.

To all whom, it may concern.-

Be it known that I, CHARLES CLAMOND, a citizen of the Republic of France, and a resident of Paris, France, have invented certain new and useful Improvements in Machines for Incinerating, Baking, and Shaping Incandescent Gas-Light Mantles, of which the following is a specification.

This invention has reference to a machine for incinerating, baking, and shaping mantles for incandescent gas-burners; and its object is to provide a machine that will perform the operations of burning, baking, and shaping mantles in a much more uniform and perfect manner than has heretofore been possible with the usual hand operation.

Prior to my invention the operations above specified have been performed entirely by hand. The operator was provided with a simple Bunsen burner, in the flame of which he held the impregnated mantle until the textile material was burned away, leaving simply the refractory skeleton. The operator thereupon introduced the flame of the burner into the interior of the mantle to expand the same to a certain extent and then baked the mantle. During the baking oper ation the operator permitted the flame to play against the inside surface of the lower edge of the mantle, so as to bow out this edge and give it something of a-bell shape.

In my invention 1 provide a machine for performing all of these operations automatically, and, whereas under the old practice an operator was necessary for attending each burner and each mantle, in my invention a single operator may attend a number of burners working upon a number of mantles. Furthermore, I do not rely upon a single burner, but I use several burners, each adapted for the especial kind of work which it has to perform. Thus I use an incinerating-burner, preferably carrying a hook or other device to which the top of the mantle is attached. This burner is especially designed for burning off the mantle, which is the first operation of the series. I further provide a separate burner, which is especially adapted to be introduced into the interior of the mantle for expanding and baking the same after the mantle has been burned off. Finally I provide a third burner, which gives a flaring flamefor coacting more especially with the bottom of the mantle, thus blowing it out and giving it a bell shape.

For convenience merely I may designate the first burner, which burns off the mantle and performs the first step of the operation, as the incinerating-burner, the second burner the bakingburner, and the third burner the flaring-burner. ggg; The baking and flaring burners in my apparatus are preferably mounted on a slide in a base-board, so that they may alternately be placed into action. The incinerating-burner is mounted on a carrier which moves up and down with reference to the base-board. This carrier is connected to a clockwork or similar device, by means of which the carrier can be moved rapidly downward by the operator to wind the spring or other propelling means, and when the pressure of the operators hand is released the carrier moves slowly and gradually upward away from the base. I also provide a series of valves to feed these separate burners and a pilot-flame which is arranged in a position to ignite each of them. The connections to these three burners and the pilot-flame are controlled by a threeway valve. When the valve is in its first position, gas is supplied to the incinerating-burner. hen the valve is in its second position, gas is supplied to the baking-burner, and when the valve is in its third position gas is supplied both to the flaring-burner and to the incinerating burner.

The three-way valve is supplied by another valve, which is operated automatically when the carrier for the incinerating-burner is moved downward. The pilot-burner is controlled by a valve which is operated by the carrier in the same way.

The operation will now in a general way be understood. A mantle which has been soaked with a solution of an incandescing material is placed on the hook or other support mounted upon the incinerating-burner. This burner, as I have above indicated, is mounted on a spring-impelled carrier. The operator now pushes down the carrier, thereby operating the valve which admits gas to the three-way valve and also operating the valve which admits gas in increased quantities to the pilot-flame. The three-way valve being in position to feed gas to the incinerating-burner, the projected pilot-flame will ignite the incinerating-burner, and the flame of the incinerating-burner will thus burn off the mantle, the action being from the top downward. During this time the carrier for screw 151.

erator returns to the machine, the burning off of the mantle having been completed and the carrier having moved back to its topmost position, she pushes the three-way valve so.

as to feed gas to the baking-burner and again pushes down the carrier. The mantle which has been burned off is thus pushed over the outside of the baking-burner, the baking burner is ignited by the pilot-flame, and during the slow rise of the carrier the mantle is completely baked. When the operator again returns to the machine, she turns the threeway valve to the position in which gas is fed both to the flaring-burner and to the inciner- She also moves the slide on which the baking-burner and flaring-burner are mounted so as to put the flaring-burner into the position previously occupied by the baking-burner. When then she pushes down the carrier, it will be seen that the flaringburner and the incinerating-burner are both in operation. The flaring-burner acts to expand the mantle, and it especially acts on the bottom of the mantle to bell it out and expand it. This finishes the operation.

In the drawings, Figure 1 is a perspective view of the apparatus as a whole. Fig. 2 is a perspective view of the apparatus, taken from the other side with parts of the supportingtable shown in section. Fig. 3 is a schematic detail of the gas connections. Figs. 4 and 5 show different positions of the three-way valve. Fig. 6 shows a handle and switchboard used for operating the valve.

The incinerating-burner 1 may be of any type. I prefer, however, to use a form of Bunsen burner covered by Letters Patent No. 574,805 to Kern, because such burner produces a far better mixture of air and gas and a far more perfect combustion than any other form.

The incinerating-burner 1 carries a hook 11, from which to support the mantle. The burner 1 is carried by means of the arm 12 on a tubular support 13, which is adjustably screwed to the standard 14 by means of a split collar 153 and the adjusting-screw 152. The standard 14 is adjustably secured to the carrier-standard 16 by a sleeve 15 and a set- The carrier-standard 16 has a rack 17 formed on its side, which coacts with the gear-wheel 18 in the box 19. There is a spring clockwork and fan arrangement 191, controlled by a ratchet 20, so arranged that when the carrier-rod 16 is pushed downward. the spring is wound and the pawl slips idly on the cooperating ratchet 20. The pressure being released from the carrier-rod 16, the pawl is now in action, and the spring, which has been wound, slowly moves the rod ppward, the motion being restrained by the The baking-burner 21 and the flaringburner 22 are secured to a slide 23. The baking burner may be cylindrical on the outside. It communicates with an orifice which is fed by a mixing apparatus of the Kern type, as before referred to and as indicated in Fig. 3. The flaring-burner 22, however, has attached at its upper end a piece 24, which acts to dish out the flame. This dishing-piece 24 is rendered adjustable by being threaded on a screw 25, projected from the body of the burner 22. As well indicated in Fig. 3, these burners 21 and 22 alternately communicate with the mixing apparatus 27, secured to the. under side of the table on which the apparatus is mounted. When the slide is in one position, the part 27 feeds the burner 21. When the slide 23 is in the other position, the part 27 feeds the burner 22.

We have now to describe the arrangement of the valves, which are fully indicated in Fig. 3. Gas is supplied by the main pipe 30 to the valve-chest 31. This valve-chest has a valve-seat 32, within which works the slidevalve 33, carried on an arm 34, on which arm are stops 35. Projecting from the valvechest 31 there is an exit 36, feeding the gas to the valve-chest 37, having a valve-seat 38, against which works a valve 39, mounted on a rod 40, which rod is supplied with a stop 41. A spring 421 normally forces this valve upward; but there is a slight leak at all times, permitting gas to pass through the passage 42 to the pilot-burner 43. It will be understood, therefore, that the pilot-burner is always burning with a small flame.

The space 310 connects with the pipe 311, which feeds gas to the three-way valve 312. This valve is connected with a supply-pipe 313 for feeding the part 27 and with the supply-pipe 314 for feeding the incin eratingburner 1.

The carrier-rod 16, with its rack, is diagrammatically indicated in Fig. 3 and supplied with arms 161 for working against the stops 35 and 41. It will be remembered that this red 16 moves with the burner 1 and mantle-support 11. When now the operator has fastened a mantle which has been soaked in an incandescent solution onto the hook 11, she presses down the standard 16 to its full extent. The arm 1'61 acting against the stop 35 opens the valve 33 and allows gas to be fed to the three-way valve through the passage 311. The rod 34, carrying the valve 33, works frictionally in its stuffing-box, so that the valve remains in its open position. At the same time the arm 161, operating against the stop 41, momentarily opens the valve 39 to feed an increased supply of gas to the pilot-flame. A long jet of flame issues from the pilot-burner and ignites the incinerating-burner. The flame from-the incinerating-burner gradually burns off the mantle, working from the top downward. Dur- IIO ing this timejthe carrier 16 is gradually moving upward, and whenthe incinerating has been completed the carrier has reached its topmost position. At this point the arm 161, working ag'ainst'the upper stop 35, closes the valve 33 and extinguishes the flame in the burner 1. The pilot-flame, however, assumes its normal proportions the instant that the carrier 16 has begun its rise, this be ing accomplished by the spring 42.

The operator, who during the period of burning off the mantle above referred to may devote her attention to other apparatuses operating on other mantles, now returns to the machine and turns the three-way valve 312 into the position shown in Fig. 4, gas being turned to the baking-burner 21 alone. She thereupon again depresses the carrierrod 16, so that the mantle which has been burned off and which has been somewhat shriveled by the operation passes over the outside of the burner 21. The carrier hav ing been depressed to its full extent, the arm 161 again operates the pilot-valve 39 and the valve 33,to now feed gas to the burner 21 and to ignite the burner 21 by the pilot-fiame. During the slow rise of the carrier-rod 16 the flame of the burner 21 is playing on the inside of the mantle and thoroughly and uniformly bakes the same throughout its whole extent. When the carrier-rod 16 has again reached its topmost position, the arm 161, again operating against the upper stop 35, cuts oil the supply of gas to the three-way valve. The operator now again returns to the machine and pushes the slide 23, so as to throw the burner 21 out of register with the chamber 27 and to throw the flaring-burners 22 into register with the same. At the same time she puts the three-way valve into the position shown in Fig. 5, where gas is fed to the incinerating-burner 1 and to the chamber 27, and thus to the flaring-burner 22. She again depresses the carrierrod 16. Thereupon the flame from the burner 22, being of a flaring character, expands the mantle, and especially bells out its bottom, and the flame from the burner 1 completes the baking.

The switchboard shown in Fig. 6 is intended to control the position of the threeway valve. The arm 315 is rigidly connected with the valve 312 and can readily be placed in any one of the three positions required, which may be indicated on the switchboard 316 in any convenient way.

It will be seen that by this apparatus I not only produce mantles which are baked and shaped much more uniformly than can be done by hand, but I do this in amanner which is largely automatic. Thus I save the time of many operators, one operator being enabled to do as much work with a group of these machines as ten operators are able to do when working by hand.

The mantle-carrier has a quick movement toward the burner, so that the operator need waste no time in adjustment, and a slow and uniform movement away from it to enable the mantle to be properly baked at all points. This I call for convenience a quick and slow movement.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-
